adel al—jubeir also said the whereabouts of the journalist's body is unknown by his government. mr al—jubeir promised mr khashoggi's family that those responsible will be held accountable. there obviously was a tremendous mistake made and what compounded the mistake made and what compounded the mistake was the attempt to cover up. that is unacceptable. these things u nfortu nately that is unacceptable. these things unfortunately happen. we have been very clear we will leave no stone unturned. the relationship is important. when the facts are revealed, we will know who is responsible and see those individuals being punished and we will put procedures in place to stop this from happening. meanwhile turkey's president erdogan has promised that on tuesday he will reveal more details of mr khashoggi's death. germany, france and the uk have issued a joint statement denouncing the killing. here's out diplomatic correspondent, james robbins.

new pictures have now emerged of jamal khashoggi walking towards the saudi consulate in istanbul, and towards his death. more and more countries are now demanding the truth, the whole truth. the saudi explanation that he died in a fist fight has been all but rejected by many governments. and where is his body? europe's three major powers have now come together to condemn the killing in the strongest possible terms. their joint statement says. .. they continue... the world is waiting for turkey and its president. he is in a position

to reveal much more. turkey's police and security services are leading the investigation and have already leaked stories of torture and murder by saudi officials. the president is pointing to revelations on tuesday. translation: we are seeking justice, and this incident will be entirely revealed, entirely. why did 15 people come to istanbul? why were 18 people arrested? this must be revealed in detail. will the slowly unfolding story increase suspicions about the role of this man, saudi arabia's prince mohammed bin salman? many people insist he must have authorised the targeting of his most vocal critic, jamal khashoggi, and will saudi arabia really be punished by other major powers, as a big spender and energy supplier? most governments are waiting for fuller answers before deciding. russia's president vladimir

putin says he wants clarification from the us after donald trump scrapped a cold war weapons treaty. the intermediate range nuclear forces treaty, or inf, dates back to 1987. it bans moscow and washington from developing missiles with nuclear warheads. mr trump says the russians have simply not honoured the deal. but russia's deputy foreign minister insists that's not true — and warned that withdrawal ‘would be a very dangerous step‘. and the former soviet leader mikhael gorbachov, who negotated the treaty with president reagan, said ditching it showed a ‘lack of wisdom' on the current president's part. we'll have the very latest from moscow injust a moment — but first, here's our washington correspondent, chris buckler. a moment and an image that let the

world know that the cold war was coming to an end. three decades ago, the then american president and soviet leader agreed the intermediate—range nuclear forces treaty that led to hundreds of missiles in both countries being destroyed, but that was a different era. while the nuclear threat isn't what it once was, for years, america has been concerned about russia's testing and deployment of a cruise missile that it says breaches the treaty. and with concerns that other countries including china aren't tied by the accord, donald trump says he's had enough. we're not going to let them violate a nuclear agreement and go out and do weapons and we're not allowed to. we're the ones that have stayed in the agreement, and we've honoured the agreement, but russia has not unfortunately honoured the agreement, so we're going to terminate the agreement and pull—out. the president has spent the week campaigning ahead of next month's crucial congressional elections. he has visited troops,

posed with missiles, and now he's talking tough about russia. some will say he's thinking about domestic concerns as well as international ones, and there some members of his own republican party worried about mr trump undoing the work of one of his presidential predecessors. i think it is a big mistake to flippantly get out of this historic agreement that reagan and gorbachev signed. it was a big part of reagan's legacy and we should not get rid of it. the us national security adviserjohn bolton is visiting moscow where he will meet with russian leaders. they already know what he plans to say. over the last year, president putin has accused america of bad faith and attempting to destroy the treaty. translation: they are constantly searching for some violations from our side, and are consistently doing it themselves. mikhail gorbachev, who signed the treaty with ronald reagan, today warned that withdrawing from the agreement was a dangerous step backwards and threatens what was once seen as a

historic leap forward. for more on this i am joined by nikolai sokov, a seniorfellow at the james martin center for nonproliferation studies, that's in the united states. nikolai joins me now from moscow. welcome. thank you for being with us. welcome. thank you for being with us. what do you make of the timing of this? why is america deciding to pull out of the treaty now? well, i would say an no real particular... i'm sorry, the reason to do this at this moment, nothing has changed over many years. i would really say to many people in the trump

administration simply do not like treaties. they have finally got their way. the reasons are ideological, psychological, buti would not see it as a strategic choice. when president obama was president, he threatened to pull out as well. it is notjust a party political ground issue. no, i would not say that. president obama did not say that. president obama did not threaten to pull out, he raised the question about russian violations. even during the obama term, the united states does not provide too many details. more importantly, the two parties simply failed to use or establish the verification... when there are

concerns of possible violations. i would say there was a way but there was no will. president obama in 2014, he accused russia of breaching the treaty after it launched a missile and he discussed pulling out of the treaty but he was persuaded by european union leaders not to do so. by european union leaders not to do so. are there any grounds that russia have breached the rules of the treaty? people in washington privately told me there are solid grounds. i know them personally. the public data has been scarce. what about china? public data has been scarce. what about china ? what public data has been scarce. what about china? what about china's position in all of this? this is between united states and russia and that are concerns that no other country is bound by it, they are

pursuing their own arms race and america is not able to do anything about it. i would not say that the united states cannot do anything about it. specifically the united states does have every right, it is not limited by any treaty. and, in fa ct, not limited by any treaty. and, in fact, the only type of asset, the ground launched once, the united states to not have too many places to deploy them. 0k. .. thank you very much for your analysis there. thank you. let's take a look at some of the other stories making the news... rival protests are taking place in the eastern german city of dresden, where counter demonstrations have been mounted to oppose a gathering of the far—right, anti—islam pegida movement.

with guatemala using makeshift rafts, after police stopped them from crossing the frontier bridge. the bbc‘s ana gabriela rojas is travelling with the group who have now made it into mexico, shejoins us now live. wellcome. just explain the background to this. why these migrants have left their home country and what they're hoping achieve. there is no doubt it is a desperate situation for them. i cannot imagine how these people have left their country, to wok in these conditions. they have been walking for ten days. the conditions are really ha rd. for ten days. the conditions are really hard. they have small children with them, some people who are sick, older people. despite that, they came. they say there is a lot of poverty. they have no job opportunities. the poverty is really bad and also violence. the organised crime they're really make trouble for them. they kill people they ask

for them. they kill people they ask for money further business. so many have been sent home, turned back by mexican police. many have also made it through, haven't they? yes, i am at this park in a city 30 kilometres from the border with guatemala. this is the exact method and step for them. it means they are in mexico. -- is them. it means they are in mexico. —— is city in mexico. some arejust arriving. some are arriving in the park and they are very happy to be here and the wish to continue. being here and the wish to continue. being here gives them the opportunity to demonstrate with the authorities to maybe allow them to growth through to the united states, as they are hoping. they think there they will have better living conditions. these economic migrants are part of a group of people that donald trump wa nts to group of people that donald trump

wants to stop. this is why he is trying to build this wall with mexico, isn't it? there are two groups. one of them are still in the border asking for refugee status from the mexican authorities and some of the made it, despite the effo rts some of the made it, despite the efforts to stop them, they went through a bridge, swimming or through a bridge, swimming or through a bridge, swimming or through a makeshift boat. thank you very much for updating us there on what has been cold a caravan of migrants who have now arrived, many of them in mexico. stay with us on bbc world news, still to come... a competitor at the invictus games breaks royal protocol to give prince harry a hug — that lifts him right off his feet. an historic moment but many of his victims waited for four decades. the

vladimir putin says he wants clarification — after president trump says he is withdrawing from a cold war—era nuclear treaty that led to the destruction of thousands of tactical nuclear missiles. france, britain and germany have strongly condemned the killing of the saudi journalist jamal khashoggi in his country's mission in istanbul, and called for urgent clarification of exactly what happened. at least 18 people have been killed and more than 160 are injured in a train derailment in northern taiwan. 366 passengers were riding on the eight—carriage train when it came off the tracks near xinma station. rescuers have brought out all of the passengers after searching for hours well into the night. the accident is the deadliest seen in the country in nearly three decades. cindy sui reports from taipei. lying off the tracks and on its side, this is a carriage train derailed so violently that it was

left in a zigzag heap. the train was packed with 366 passengers, many of them heading home after a weekend away. some passengers managed to get out on their own, but many others could not escape. firefighters tried to get inside the carriages to find survivors but the task was made difficult because several carriages had been overturned. besides those confirmed killed and injured, rescu e rs confirmed killed and injured, rescuers spent hours trying to find people feared to be still trapped inside. as night fell, they used flashlights to search inside in overturned carriages for any survivors. translation: i heard a loud bang and came running up. residents were helping people get away. then the ambulances arrived. we were directing

ambulances to leave quickly for the hospital. the administration is investigating the cause. officials say it is not clear if the accident was caused with a problem on the tracks or a train. local media reported that passengers have said the train has stalled a feud times and then accelerated before it derailed. tie one is also seeking a nswe rs derailed. tie one is also seeking answers as why it's really network could have experienced such a serious accident. —— the government is seeking answers. the uk government has suggested that any extension to the brexit transition period should be about three months long. britain's brexit secretary dominic raab also called on mps from his conservative party to pull together and, as he put it, hold their nerves. our uk political correspondent, chris mason reports. chanting: what do we want? people's vote!

when do we want it? now! a day on from this — hundreds of thousands of marchers demanded another referendum on brexit — today, it's back to the political slog of trying to reach a deal with the european union. and a slog accompanied by a noisy soundtrack of grumbles from the conservative backbenchers. so, the brexit secretary pleads... it's understandable that there are jitters on all sides of this debate. we need to hold our nerve. the end is in sight in terms of a good deal. the prize that we want — a good deal with eu. and those jitters go something like this when you stare across the channel. this withdrawal agreement is almost ready, but we still have to fix the question of the irish border. and we have to have a definitive answer, or at least no temporary measures which disappear and we don't know what to do after that. the current plan if there's a withdrawal agreement with brussels is for a transition period after brexit lasting until the end of 2020.

but, the government accepts that might now have to be longer, as it thrashes around for a plan it and the eu can live with to keep the border with ireland open. ministers are suggesting a so—called backstop, where all of the uk stays in a customs arrangement with the eu until the government decides not to. but that, mr raab said, could come after an extension to the transition period of three months or so. it's an obvious possible route. but as long as its short, perhaps a few months, and, secondly, that we know how we get out of it. and obviously it has the solve the backstop issue so that that falls away then as a possibility. if a deal is done with the eu, it'll need to be approved by parliament. and given some on her own side don't like what's being cooked up by the government, the prime minister might need some labour mps to vote for it. but... we're not going to accept that this argument that it's either my deal or no deal, because on that logic,

you would be putting to me that the labour party should back anything that the prime minister brings back. and the slog continues. and it gets noisier by the week. now for the sports news. well, the title race continues. all eyes had been on lewis hamilton at the us grand prix — where he could have taken his fifth world championship title — it wasn't to be for the mercedes driver, but what a dramatic finish in austin. hamilton needed to finish eight points clear of his title rival sebastian vettel, and with just over two laps to go and vettel in fifth, third placed hamilton attempted one final attempt to overtake max verstappen in second but he went wide. meanwhile, vettel moved into fourth — ensuring the title race moves on to mexico. the race was won by ferrari's kimi raikkonen. his first gp win in five and a half years. meanwhile, on two wheels it's

already been decided — a fifth title has been won in moto gp by marc marquez. it's also the spaniards third in a row... sealed with yet another victory injapan and celebrated in a slightly more painful style than you might expect. claire thornton reports. racing on the circuit where he already won two titles, he wasn't going to be put off by starting six on the grid. his nearest championship rival had the advantage of starting on pole position. it wasn't long before the honda rider made his way to the front and attend stewart between the pair dominated the race. with only four laps to go, marquez made his move. the race was not over. the consequences proved costly. with the battle won, marquez

raced onto his fifth world title, savouring every second of his final lap. the drama did not stop there. emotions of the occasion and overzealous celebrations resulted in marquez dislocating his shoulder. treatment sorted him out and the party started on the podium. treatment sorted him out and the party started on the podiumlj treatment sorted him out and the party started on the podium. i feel really, really good. i was a champion and i are ready —— i already felt so. the good thing is the difference is when you have the chance. marquez should feel good. he is in good company, with only two more legends having one more titles than him. golf has a new world number one. brooks koepka will replace dustinjohsnon at the top of the rankings with another victory

in south korea today. the american held a four stroke advantage going into the final day in the cj cup. and managed to maintain that thanks to five birdies on the back nine... including that chip and run on the 16th. and then he finished in style with an eagle on the 18th. koepka's also won the us pga and us open titles this year. it isa it is a battle every day. you have to keep working hard to try and improve. i enjoy my time in the european tour and to finally get over here on the tour and to be well number one is something i dream job asa number one is something i dream job as a child and i do not think this one is going to sink in. australian open champion caroline wozniacki got the defence of her wta finals title off to the worst possible start. the dane was beaten in straight sets by karolina pliskova in singapore. pliskova, a former world number one, wrapped up her opening group victory with an ace and she'll meet elina svitolina next —
